Karakhanyan confirmed Robinson’s injury via Twitter, and a source close to the event told MMAjunkie.com Leone has been tapped as a replacement.

Bellator 28 takes place Sept. 9 at the Mahalia Jackson Theater for the Performing Arts in New Orleans.

Leone vs. Karakhanyan likely will be part of the night’s FOX Sports Net-televised main card.

Leone is the third opponent for Karakhanyan. Prior to the Robinson booking, he was slated to fight Chas Skelly, a Texas-based ground specialist who was forced off the card due to a foot injury.

Karakhanyan entered the Bellator season-two featherweight tourney earlier this year, and in the first round, he topped notable Bao Quach via first-round TKO. The victory extended his win streak to a remarkable nine fights. However, in the semifinals, he suffered a decision loss to eventual tourney runner-up Joe Warren and was bounced from the eight-man field.

Leone signed with the WEC earlier this year and made his promotional debut at WEC 49. However, his perfect 8-0 record took a hit when fellow WEC newcomer Renan do Nascimento Mota Pegado (23-1) posted a third-round submission win.
